This is an updated version of my box clamp that I previously posted .
http://lumberjocks.com/projects/107614
The improvements are the clamping arms which enclose the strap an is also reduced to two slots which makes the strap exit on the ouside where the clamp can grab the strap and I also added a dowel to act as a hinge point to keep the arms from sliding past each other during clamping .!

The second improvement is a strap guide which is comprised of two washers on each of the eight pins this is to centre the strap and accomplished by changing the upper and lower spacer size .

The third change is the inside corner opening enlargement which now makes it possible to clamp finger jointed and dove tail joint boxes by providing the necessary clearence .( See picture and picture #6 )

The fourth improvement is I found a way to make the strap ends the same size as the the rest of the belt and make it easy to insert into the clamp arm slots by applying a bead of CA glue about 1/2” wide and letting it dry and then trimming the end by cutting across the strap through the glued area .This gives me a nice and smooth and stiff end which is easy to insert into the slot .

All changes are made to the existing parts except for the clamping arms which I made new but could have used the existing also .

Thanks for looking

Klaus

I made a set and they worked very well but I did have a few issues that detracted from the pleasure of using them.
You have cleared them all up in this update.
Mine are already altered, some alterations are my own and a couple are Klaus’s suggestions but they are now very easy to use and reliable clamps.

Thanks buddy.

Great clamps, Klaus…...I gotta make me a set of these. Is it possible for the sides to slide by each other when you are doing butt joints?

Hi Klaus,

A great box clamp can come in very handy. What kind of joint are you using in the last photo? It looks like a butt joint in the photo, but from your text it sounds like it is either a finger joint or a dovetail.

Thanks for sharing!

Thanks all for your supporting comments !
Paul thanks for your inspiration on some of the updates it always helps .

John
For butt joints you could add a board to the ends as a spacer with the new corner or use the original corner design . (see picture )

I made a set similar to your first version but haven’t used them or really tested them. Side tracked on family to do projects. Thanks for the update improvements. I will hopefully get to them soon. Thanks Klaus.

Kiefer I think you should write a book. A woodworking publisher would be crazy not to snatch it up.
